It’s a cliche, but it’s worth discussing again: How to save yourself after an earthquake?

Blockquote > You are eating a hot pot and singing. Suddenly, you feel the ground shaking violently. You make the first judgment: the earthquake! So, what should you do? Don’t tell me screaming is your first choice! We are most concerned about our readers. How can we keep secret books for survival and not share them with you?

I am familiar with four books and five classics, and I am also an incurable rationalist and obsessive-compulsive perfectionist, totally intolerant of all non-scientific and irrational things – so “naive” is the comment I often hear.

In recent years, the word “earthquake” has appeared so frequently that some people joke that the earth has been tuned into a mode of vibration. In fact, earthquakes occur every day on the earth, but most of them have not been paid attention to because of their small magnitude or occurring in unmanned areas such as oceans. According to statistics, there are about 5 million earthquakes on the earth every year, of which there are about 18 earthquakes with magnitude 7 or above.

My professional direction is not to study earthquakes, but to deal with wounds and heal the wounded. So you can obviously guess that what I want to teach you is not to be a “magic stick” to predict earthquakes, but to save yourself in case of an earthquake.

Don’t worry meaninglessly. Please use the following words as a secret book for a RPG game. Remember, even if it’s hell-class, you still have a chance to survive!

Strong > < strong > Stage 1: Earthquake! Where am I? .

When you first feel an earthquake, the first thing you have to do is not scream. Think about it. Like starting a new adventure game, the first thing you need to do after the first shock is to judge your environment.

If you happen to be in a building that is easy to escape to an open area, such as a farmhouse or warehouse, and the building is not strong and has a high probability of collapse, you should rush out of the room and run to the open area as soon as possible. In this case, be sure to run resolutely, decisively and sharply. Don’t worry about going back and getting things. What? You said you were going back to get the homework you had to hand in the next day? Okay, I lost you completely!

For urban building tenants, staying in the room is the best choice. Jump off building? Absolutely the most foolish option. Even if you are lucky enough not to fall dead on the spot, the high-altitude falling caused by the earthquake is enough to kill you. At this time, you should consider yourself a Ninja tortoise and hide in the small space of the building near the load-bearing wall.

Many earthquake examples at home and abroad show that people are most likely to be killed or injured when they enter or leave buildings in the short time of an earthquake. Generally speaking, reinforced concrete buildings are not only rigid, but also resilient. They are generally not completely destroyed in an earthquake. In the first minute of escaping danger, there is hope of survival.

If you are unfortunately in a tofu dregs project that collapses in an earthquake, it is also very likely that you will be buried in the corridor when you run out. When evading in the building, immediately hide under the solid furniture or at the base of the load-bearing wall. Generally speaking, places with more load-bearing walls, less space and more metal pipes are the safest, such as toilets. If possible, try to cut off the electricity and put out the fire extinguishing source.

Strong > < strong > Stage 2: Ordinary difficulty – Oh, Yeah! I’m outside! .

Thankfully, the terrible earthquake has finally passed, the earth has calmed down, you slowly climb out of hiding place, full of happiness for the rest of your life. Faced with the blackness caused by the power interruption, you shivered out of your pocket the lighter intended to illuminate — “Hang!” You ignited the natural gas leaked from the rupture of the natural gas pipeline. Fire, a very common secondary disaster after an earthquake, is induced by you. How will the result be? I believe you can find a lot of information.

After the earthquake, if you are not trapped, don’t make an open fire, and don’t venture around, it is likely to touch bare wires. To rescue the trapped people, we must first ensure our own safety. If an earthquake occurs during the day, with a good view and no injury to yourself, you can help the people around you as much as possible, and then quickly escape from the lifeline. By the way, take some water, food and clothing, but don’t take up too much time. Take the stairs. Don’t worry about the elevator at this time.

When you finally get out of the building, don’t think there’s no danger. Narrow streets and tall buildings in the city may drop building materials, glass fragments, billboards and neon lights at any time! All of this will pose a threat to you.

In addition, do not close to riverbanks, canals, steep walls, cliffs, bridges, away from high-voltage wires, transformers, as far as possible to parks, playgrounds, fields and other open areas to avoid.

When you get to the above places, congratulations to you, you can clear the customs ahead of time!

< strong > strong > Stage 3: Hell Difficulty – Oh, No! Buried! .

It’s an unfortunate possibility, but we have to think about it more. If this happens, all you have to do is to build up confidence, ensure safety, save energy, and inform the outside world.

First of all, you need to calm down quickly. Any negative, self-abandoning, hysterical mood is the enemy of survival. Kin, come on, in order to make the people who love you not sad, in order to make the people who hate you unhappy, courageously persevere. Who, don’t laugh! When you are in trouble, think about it more. It can be a motivation for you to stick to it.

In order to ensure their own safety, do not easily use lighters, matches and other things. It’s not fun to ignite flammable materials around you even without a natural gas leak. After all, you’re trapped in a very narrow space.

The small space you live in may be very unstable, and if you want to survive, you must not let it collapse. If your clothes or parts of your body are pressed down, don’t rush to break away. First, calm down and study the structure of your space carefully. Any space must have a stable supporting structure. Let’s make it clear first. Violent break-up and pull is likely to lead to the collapse of the whole space, which will instantly ruin your chances of survival.

Once you know enough about the support and firmness of your shelter, you can take measures to restore freedom to the extruded area without destabilizing the situation. Remember, if you can’t, don’t force it. It can be reinforced with materials available around it, such as bricks, wood, etc., while clearing the unstable things above the body to avoid injury.

If you smell gas or the dust in your environment is very serious, you can cover your mouth and nose after wetting your clothes. No water? Limited drinking water? I know you must have thought about what to replace. Must I say it? Well, use urine – you really don’t feel dirty, it’s just waste from your body.

If there is active bleeding in the wound, you can tear the clothes into strips and pressure bandage to stop bleeding. If there is a limb fracture, if conditions permit, clothes can be used to tie the stick to the fracture site, so as to avoid fracture dislocation, causing vascular damage, leading to massive bleeding and other serious secondary injuries.

Now, take a breath, you have to find a way to win the next long battle! After temporary safety, try to conserve your strength so that you can maintain it for as long as possible.

Don’t yell. It’s a waste of energy to do so without rescuers arriving. Check the food and drinking water around you and try to use it as economically as possible in a planned way. If you don’t have food and drinking water, you can look around for some natural food: beetle larvae (commonly known as grubs) can eat, locusts and cockroaches also have low protein content, earthworm geckos can be considered real meat… Have you seen “Survival in the Wild”? That great God must be an example for you to learn!

If you want to get rescue, you must also inform the outside world of your location information. Turn on your cell phone, if there is a signal, congratulations, your chances of rescue will be greatly increased. Call now and inform each other of your situation and location information so that the rescue team can arrange rescue. Don’t be too disappointed if the cell phone doesn’t have a signal, because the signal interruption caused by the earthquake is normal. You should turn off your cell phone to avoid excessive power consumption and turn it on every six or seven hours. Once the communication system is repaired and the cell phone has a signal, you can immediately contact the outside world.

When you hear someone outside, you can send a signal by tapping and so on. When rescuers find you, sometimes because of the complex situation of the collapsed objects, they may not be able to rescue you immediately. At this time, they should wait patiently and try to inform the rescuers about themselves and their space.

I hope that all people will not need to use this knowledge in their lives. But we also want you to remember that – maybe it will save you in an emergency.
